Deleted Robocall Blocker App But It's Still Blocking When I Don't Want It To!

Hi, I have an iphone13 pro that was getting a bunch of calls from numbers and I decided to download a robocall blocking app. No, I can't remember which one it was. If Apple had a way of storing all the apps you've downloaded to your phone, that'd be helpful but right now I don't know what to do.

I was hoping a software update would phase it out of the system but it's still doing this same crap. Im super ****** because I just missed out on potential employer calling me back for a follow up interview and have no way to return the call. If anyone knows what to do to get this to stop, please tell me.
